Want to learn Lightroom, Aperture, Photoshop, or practically any other major software title? The folks I teach for, lynda.com, offer a 7 Day Trial Period if you sign up. If, after the 7 days of mind-bending training, you decide that lynda.com isn't for you, then just cancel your membership with no obligation.
My training titles on lynda.com include Aperture 3, iPhoto '11, Off-Camera Flash, Portraiture, Getting Pro Results from a Compact Camera, and more.
Each title is presented to you in a series of short, digestible movies that you can watch over and over again until you master that particular technique. I organize the movies in a clear table of contents format, so you can go directly to the technique you're most interested in at the moment. If you want to watch the training from start to finish, then we keep the pace fast and informative helping you absorb as much information as possible.
I have new titles coming out this year, including a revised Flickr training and a live-action training on how to improve your Group Shots. Stay tuned for those debuts.
In the meantime, take a look at what lynda.com has to offer via the 7 Day Trial Period. It's really quite impressive.
